Step-by-Step Operating Procedures
Pre-Treatment Preparation
Before initiating any hemoperfusion procedure, complete these essential preparation steps:
1. Equipment Inspection: Verify all system components are properly connected and functioning. Check for any visible damage to tubing, connectors, or the main unit.
2. Cartridge Selection: Choose the appropriate hemoperfusion cartridge based on the specific treatment indication and patient characteristics.
3. Prime Solution Preparation: Prepare sterile saline solution according to facility protocols. Ensure solution temperature is appropriate for patient comfort.
4. Patient Assessment: Confirm vascular access adequacy and patient stability before connecting to the extracorporeal circuit.
System Setup and Priming
1. Cartridge Installation: Mount the selected hemoperfusion cartridge securely in the designated holder. Ensure all connections are tight and properly sealed.
2. Tubing Connection: Connect arterial and venous blood lines according to the color-coded system. Double-check all connections for security.
3. System Priming: Fill the extracorporeal circuit with priming solution, ensuring complete air removal. Monitor pressure readings during priming to verify proper flow patterns.
4. Parameter Setting: Input patient-specific treatment parameters including blood flow rate, treatment duration, and alarm limits.
Treatment Initiation and Monitoring
1. Vascular Access Connection: Connect the patient’s vascular access to the prepared extracorporeal circuit using sterile technique.
2. Treatment Start: Begin blood flow gradually, monitoring patient tolerance and system parameters. Increase flow rate to prescribed levels over several minutes.
3. Continuous Monitoring: Observe pressure readings, flow rates, and patient vital signs throughout the treatment. Document parameters at regular intervals.
4. Parameter Adjustments: Make necessary adjustments to maintain optimal treatment conditions while ensuring patient safety and comfort.
Post-Treatment Procedures
1. Blood Return: Return patient blood to the circulation using appropriate return solution. Monitor for any adverse reactions during this process.
2. Circuit Disconnection: Safely disconnect the patient from the extracorporeal circuit following established protocols.
3. System Shutdown: Complete proper shutdown procedures, including data recording and equipment decontamination.
Safety Precautions and Risk Management
Critical Safety Protocols
Operating the Jianfan Hemoperfutor requires strict adherence to safety protocols to prevent patient complications and ensure effective treatment outcomes.
Anticoagulation Management: Maintain appropriate anticoagulation levels throughout treatment to prevent circuit clotting while minimizing bleeding risk. Monitor coagulation parameters regularly and adjust heparin dosing as needed.
Pressure Monitoring: Continuously observe pressure readings across the circuit. Sudden pressure changes may indicate circuit problems, access issues, or patient complications requiring immediate attention.
Air Detection Systems: The built-in air detection system provides multiple safety layers. Never override air detection alarms without proper investigation and resolution of the underlying cause.
Emergency Procedures
Power Failure Protocol: Implement backup power procedures immediately. The system includes battery backup for critical functions, but manual blood return may be necessary.
Circuit Compromise: If circuit integrity is compromised, immediately stop treatment and initiate emergency blood return procedures. Maintain patient vascular access for alternative treatment options.
Patient Emergency Response: Have emergency medications and equipment readily available. Ensure adequate staffing for immediate response to patient complications.
Troubleshooting Common Issues
Pressure Alarms
High pressure alarms often indicate access problems, circuit kinking, or cartridge clotting. Systematic evaluation of the blood path usually identifies the source. Low pressure alarms may suggest loose connections, access dysfunction, or pump problems.
Flow Rate Problems
Inadequate flow rates can result from access issues, patient positioning, or circuit problems. Evaluate vascular access function and patient position before adjusting pump parameters.
System Error Messages
The control system provides specific error codes for various malfunctions. Consult the error code reference guide for appropriate troubleshooting steps. Some errors require technical service intervention.
Maintenance and Quality Assurance
Routine Maintenance Schedule
Regular maintenance ensures optimal system performance and extends equipment life. Daily cleaning and inspection prevent most operational problems.
Daily Maintenance: Clean external surfaces, inspect tubing connections, and verify alarm function. Document maintenance activities according to facility requirements.
Weekly Maintenance: Perform calibration checks on pressure sensors and flow monitors. Clean and inspect internal components accessible without tools.
Monthly Maintenance: Conduct comprehensive system testing including all safety systems, alarms, and backup functions. Schedule professional service as needed.
Documentation Requirements
Maintain detailed records of all treatments, maintenance activities, and any system irregularities. Proper documentation supports quality improvement efforts and regulatory compliance.
Frequently Asked Questions
How often should pressure transducers be calibrated?
Pressure transducers should be calibrated daily before first use and whenever accuracy is questioned. Follow manufacturer specifications for calibration procedures.
What is the maximum treatment duration recommended?
Treatment duration varies based on clinical indication and patient tolerance. Most treatments range from 2-4 hours, but specific protocols should follow physician orders and institutional guidelines.
